sane-gphoto2 - SANE backend for gphoto2 supported cameras
|
|
|
|
|

</PRE>
|
|
<H2>DESCRIPTION</H2><PRE>
|
|
The <B>sane-gphoto2</B> library implements a SANE (Scanner Access Now Easy)
|
|
backend that provides access to the digital cameras supported by
|
|
gphoto2. This backend has only been tested with a handful of cameras
|
|
so far. Patches to support other models are welcome.
|
|
|
|
Because of the limited testing of this backend, it is commented out in
|
|
<I>/usr/local/etc/sane.d/dll.conf</I> by default. Either the comment charac-
|
|
ter must be removed or the backend must be called explicitly. E.g.
|
|
<I>scanimage</I> <I>-d</I> <I>gphoto2</I> or <I>xscanimage</I> <I>gphoto2</I>.
|
|
|
|
|
|
</PRE>
|
|
<H2>DEVICE NAMES</H2><PRE>
|
|
The current version of the backend only allows one camera to be con-
|
|
nected. The device name is always "0".
|
|
|
|
|
|
</PRE>
|
|
<H2>CONFIGURATION</H2><PRE>
|
|
The contents of the <I>gphoto2.conf</I> specify the characteristics of the
|
|
camera to be used. Resolutions (high resolution, low resolution, and
|
|
thumbnail size) are required since they are needed by the sane fron-
|
|
tends, but can't be obtained through the gphoto2 interface. Valid
|
|
ports and cameras can be obtained by <I>gphoto2</I> <I>--list-cameras</I> and <I>gphoto2</I>
|
|
<I>--list-ports</I> <I>.</I>
|
|
|
|
The <B>dumpinquiry</B> line causes some information about the camera to be
|
|
printed.
|
|
|
|
Empty lines and lines starting with a hash mark (#) are ignored. A
|
|
sample configuration file is shown below:
|
|
|
|
The <B>topfolder</B> line specifies the "fixed" part of the file path. For
|
|
example, on the Kodak DC-240, files are stored in the directory
|
|
<I>/DCIM/100DC240.</I> The <I>/DCIM</I> portion is constant, but 100DC240 will
|
|
change and must be read from the camera. In this case, the line would
|
|
read "topfolder=/DCIM"
|
|
|
|
Some cameras don't implement a file structure and store all pictures in
|
|
the <I>/</I> directory. This is indicated by setting "subdirs=0" with "top-
|
|
folder=/"

<H2>FILES</H2><PRE>
|
|
<I>/usr/local/etc/sane.d/gphoto2.conf</I>
|
|
The backend configuration file (see also description of
|
|
<B>SANE_CONFIG_DIR</B> below).
|
|
|
|
<I>/usr/local/lib/sane/libsane-gphoto2.a</I>
|
|
The static library implementing this backend.
|
|
|
|
<I>/usr/local/lib/sane/libsane-gphoto2.so</I>
|
|
The shared library implementing this backend (present on systems
|
|
that support dynamic loading).
|
|
|
|
|
|
|
|
</PRE>
|
|
<H2>ENVIRONMENT</H2><PRE>
|
|
<B>SANE_CONFIG_DIR</B>
|
|
This environment variable specifies the list of directories that
|
|
may contain the configuration file. On *NIX systems, the direc-
|
|
tories are separated by a colon (`:'), under OS/2, they are sep-
|
|
arated by a semi-colon (`;'). If this variable is not set, the
|
|
configuration file is searched in two default directories:
|
|
first, the current working directory (<I>.</I>) and then in
|
|
<I>/usr/local/etc/sane.d</I>. If the value of the environment variable
|
|
ends with the directory separator character, then the default
|
|
directories are searched after the explicitly specified directo-
|
|
ries. For example, setting <B>SANE_CONFIG_DIR</B> to "/tmp/config:"
|
|
would result in directories <I>tmp/config</I>, <I>.</I>, and
|
|
<I>/usr/local/etc/sane.d</I> being searched (in this order).
|
|
|
|
<B>SANE_DEBUG_GPHOTO2</B>
|
|
If the library was compiled with debugging support enabled, this
|
|
environment variable controls the debug level for this backend.
|
|
A value of 128 requests maximally copious debug output; smaller
|
|
levels reduce verbosity.
|
|
|
|
<B>GP_DEBUG</B>
|
|
Set to 1, 2, or 3, to enable various levels of debugging within
|
|
the gphoto2 libraries.
